[19] The captain and coach of the first championship winning team was Virgilio Fossati,[20] who was later killed in battle while serving in the Italian army during World War I.

After the end of World War II, the club's name changed back to its original one, Internazionale,[2] and it come close to win Serie A title in two occasions, one in the last season of Grande Torino in 1949 and in 1951 with the contribution of great players acquired by president Carlo Masseroni in these years, like the first Dutch player in club history Faas Wilkes; Inter will win its sixth championship in 1953 and its seventh in 1954, for the first time in two consecutive years, coached by Alfredo Foni and led by two of the most prolific strikers in club history: István Nyers and Benito Lorenzi with Lennart Skoglund that completed the offensive trio.

In May 1955 Angelo Moratti became the new owner of Inter and despite a disappointment start in the first years with different coaches and players, he put foundations to one of the greatest team in football history.

[28] The core of Herrera's team were the attacking full-backs Tarcisio Burgnich and Giacinto Facchetti, Armando Picchi the sweeper, Suárez the playmaker, Jair the winger, Mario Corso the left midfielder and Sandro Mazzola, who played on the inside-right.

[29][30][31][32][33] After the Serie A title won in previous season, in 1964 Inter reached the European Cup Final by beating Borussia Dortmund in the semi-final and Partizan in the quarter-final.

Inter came close to winning the Treble for the first time in European football history that year, after having also won the Serie A title, but lost the Coppa Italia final against Juventus in a game played in the last days of August 1965.

Inter again reached semifinals of the European cup in 1966, but this time lost against a Real Madrid team that would go on to win the tournament, while in national championship Herrera's squad won the tenth scudetto in club history, the first Star.

In the previous seasons in 1996–1997 Inter reached for third time Uefa Cup final losing this time at penalty in Giuseppe Meazza against Schalke 04 with Roy Hodgson that resigned shortly afterwards, instead in 1997–1998 under Simoni Inter had won his third UEFA Cup defending in Paris final Lazio 3–0 with goals from Ivan Zamorano, Zanetti and Ronaldo, and nearly won Serie A title, with many controversial referee decisions culminated in the decisive match against Juventus in Turin with Inter behind only 1 point with 4 games left, when referee didn't concede a penalty on Ronaldo and after few seconds conceded a penalty for Juventus, that generated a turmoil on the pitch and a big scandal, with president Moratti that left the building shortly afterwards.

The team came close to their first domestic success since 1989 when they reached the Coppa Italia final, only to be defeated by Lazio, in a match remembered for the second severe injury to the right knee of Ronaldo, who was returning after five months of inactivity, and which would keep him out for more than a year and a half.

Inter's misfortunes continued the following season, losing the 2000 Supercoppa Italiana match against Lazio 4–3, after initially taking the lead through new signing Robbie Keane.

Marco Tardelli, chosen to replace Lippi, failed to improve results, and is remembered by Inter fans as the manager who lost 6–0 in the city derby against Milan.

In 2002 with new coach Hector Cuper, the acquisition of the second most expensive goalkeeper in the world at that time Francesco Toldo and the return after injury of Ronaldo in pair with Vieri, not only did Inter manage to make it to the UEFA Cup semi-finals, but were also only 45 minutes away from capturing the Scudetto when they needed to maintain their one-goal advantage away to Lazio.

[40] Inter reached 2002–03 Champions League semi-finals against AC Milan, that were played also without Vieri out for injury, losing on the away goals rule with two draw in the same stadium in San Siro.

[42][43] On 11 May 2006, Inter won the Coppa Italia title for the second season in a row after defeating Roma with a 4–1 aggregate victory (a 1–1 scoreline in Rome and a 3–1 win at the San Siro).

However, a late collapse, leading to a 2–0 defeat with ten men away to Liverpool on 19 February in the Champions League,[49] brought manager Roberto Mancini's future at Inter,[50] into question while domestic form took a sharp turn of fortune, with the team failing to win in the three following Serie A games.

In the summer of 2009 Inter put foundation to maybe the greatest single season of its history: after have signed Diego Milito and Thiago Motta from Genoa, Lúcio from Bayern Munich, the club agreed to sell Ibrahimovic to Barcelona in change for Samuel Eto'o plus 49 millions euros.

[66] Leonardo led the club to the quarter-finals of the Champions League, after have defeated again Bayern Munich in Round of 16, before losing to Schalke 04;[67] Inter ended second in Serie A and won the Coppa Italia title.

a company owned by Zhang Jindong, co-founder and chairman of Suning Commerce Group, acquired a majority stake of Inter from Thohir's consortium International Sports Capital S.p.A. and from Moratti family's remaining shares in Internazionale Holding S.r.l.

[104] On 18 January 2023, Inter won the Supercoppa Italiana, defeating Milan 3−0 at King Fahd International Stadium, thanks to goals from Federico Dimarco, Edin Džeko, and Lautaro Martinez.

In July 2023 Inter sold for 50 million € goalkeeper Andre Onana to Manchester United, acquired the prior season for free, like Hakan Calhanoglu in 2021, Henrikh Mkhitaryan in 2022 and Marcus Thuram in 2023.

[108] On 22 May 2024, Oaktree Capital Management assumed ownership of Inter Milan following the default of Suning Holdings Group on a substantial loan given in May 2021 to the club in order to cover losses incurred during the COVID-19 pandemic.

[123] In the winter of 2021, Giuseppe Sala, the mayor of Milan, gave official permission for the construction of the new stadium next to San Siro, which is expected to be partially demolished and refunctionalised after the 2026 Olympic Games.

Throughout 2024, the Curva Nord (labelled as the "Curva Nord Milano") have collaborated with rap duo ¥$ (composed of Kanye West and Ty Dolla Sign) on multiple occasions, appearing as a choir on the chart-topping hit song "Carnival" (alongside rapping on its chorus) featuring Playboi Carti and Rich the Kid and on the ¥$ remix of "Like That" featuring only Future and record producer Metro Boomin (Kendrick Lamar would not appear on the remixed version of the song).

[188] In November 2018, documents from Football Leaks further revealed that the loan signings such as Xherdan Shaqiri in January 2015, was in fact had inevitable conditions to trigger the outright purchase.

[190] However, on the same day, UEFA also announced that the reduction of squad size of Inter in European competitions would not be lifted yet, due to partial fulfilment of the targets in the settlement agreement.

[193] On May 22, 2024, US-based investment firm Oaktree Capital Management said it “assumed ownership” of the club, after previous owner, Suning, a Chinese holding company, missed the deadline on a €395 million debt payment taken out during the COVID pandemic.
